wondlof ?

Given the two check/calls with the flush and boat on board, I'd be content to check this on the river.

However, I think I'd bet a lot more on the turn, at least 3/4 the pot I'd think.

Did you have any reads on this player?

Stats were 34/9 after only 32 hands. The only hand that makes the flush that I can imagine him raising pre flop with is AdJd. I'm pretty sure that he doesn't have the full house, I don't believe he is tricky enough to check call the flop/turn and then go for the check raise on the river. I think that I can get some value by getting called by AJo / AK. In the actual hand I checked and won as he mucked. He told me he had AK.

Definitely bet the river and call a standard raise.
